Chances are good that you\'ll find some damage on the boards. Either wripples or finger pushes and even holes. This damage can be repaired by using this wood fill. It is easy to sand and will bond to the paper. I successfully filled in several holes and flaws. It is important that you have a smooth surface because you are going to reapply the original headliner without foam. Any flaws will tend to show through. That is one of the reasons they used foam to begin with.
